A 2014 study from Activehealth called “Promoting Healthy Behaviors: A Five-year Study on the Impact of Incentives”, was conducted over a period of five years, included 1.9 million members across 25 large employers nationwide and compared outcomes between companies with various incentive designs to the outcomes during time periods when those companies did not offer incentives. According to the study, incentives improved health assessment/biometric screening completion: 18 percent of people filled out an health assessment without incentives while 63 percent completed an HA when incented, an increase of 250 percent.
